Has anybody ever done mocha camsolve on 30 sec?

Just asking: I have a clip about 30 sec and tracked it so far. Then I started a camsolve. Since I had an appointment I needed to abort it - after 70 Minutes from which 50 Minutes waiting at 97% (Intel I7-7700 4/4.2 Ghz). Has anybody ever done a solve so long and so has any clue how long that could take? It was pegging CPU to 60-65% so 2 cores and one thread I guess.
